Reboot to synchronize message and SQL log files [CR 467129]

If you run Sybase IQ in a country that observes Daylight Savings Time, you must reboot IQ servers after the change back to standard time. The reboot corrects a time difference between the IQ message log and the SQL log generated by specifying the -zr switch on the server startup. IQ servers also require the reboot after the change to daylight savings time.
